# CASA Space Frame 3D vs GAMMA AR

The clearest difference is price: GAMMA AR at Free against CASA Space Frame 3D's $299.99. GAMMA AR also leads on rating (4.6 vs 4.0) and update cadence (every 2 weeks vs every 3 months). CASA Space Frame 3D's advantage is review sentiment (100% vs 86%) and iOS requirement (14.1 vs 16.0). On ads, in-app purchases and device support there is nothing between them.

GAMMA AR is free to download; CASA Space Frame 3D costs $299.99 up front. Neither carries in-app purchases, so what you see is what you pay.

GAMMA AR holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: GAMMA AR has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of CASA Space Frame 3D's written reviews are positive against 86% of GAMMA AR's, so the app with the better star average is not the one people write more warmly about.

CASA Space Frame 3D ships an update every 3 months, GAMMA AR every 2 weeks. The most recent releases landed on October 23, 2026 and October 26, 2026 respectively.
